example of occlusion light on characters and environment

Here are two examples of the colour pass and occlusion pass on both characters and environment. The occlusion is the black and white image and will show where the shadows will appear on the final scene once the colour and occlusion images are put together in after effects.

Its similer to the layers in photoshop where you just place the colour on top of the occlusion and the light will show up in the final skit.

For shots where the camera was static only one image of the environment was needed, one of the colour and occlusion. but for scenes with a moving camera one for every frame had to be taken which one one particular scene took nearly 11 hours alone just to render the colour and occlusion of the background for a 3 sec moving shot.
